On the topic of the tape of the American soldier dispatching a wounded and unarmed enemy soldier with a rifle shot to the head, Instapundit makes an excellent point, as does My Pet Jawa, and most definitely Beautiful Atrocities, quoted here:
"If enough prone terrorists have fired at you, you learn to kill prone terrorists before they can pick up another gun. Simple as that. In short, you react to the tactics of your enemy, not to ethical hypotheticals—and no simpering retrospective sanctimony should obscure that very real fact."
Amen brother. Insty's right; if Kerry deserves a Silver Star for doing the same thing while beaching his craft against SOP, this guy deserves at least that if not more.
UPDATE: I should have known Captain Ed would have more, including this:
"About a block away, a Marine was killed and five others wounded by a booby-trapped body they found in a house after a shootout with insurgents."
